JIGGING-MACHINE Application filed January 22, 1912.

To all whom it may concern Be it known that I, KARL SoI-IUoI-rAnD,engineer, a subject of the German Emperor, residing at No. 2Konigshiitter Chausse, Beuthen, O. S., Germany, have invented new anduseful Improvements in Jigging-Machines, of which the following is aspecification.

This invention relates to settling machines wherein the jigging actionis accomplished by the pulsation of a stream of water to and fro througha perforated stationary carrier whereon the material to be separated issupported. Such perforated carriers have heretofore been formed as aperforated fiat sheet, but this construction however permits only of anextremely imperfect utilization of the jigging force of the water,considerable loss of energy and unsatisfactory performance of workthereby resulting.

The present invention is intended to obviate these defects. For thispurpose, the carrier is enlarged by corrugation or other suitableformation and formed over its whole surface with perforations whichallow of the jigging water not only acting vertically, or at any rateapproximately vertically but also obliquely against the material to beseparated.

The shape, length, width and depth as well as the course of theindividual corrugations, that is to say whether they run in thedirection of flow of the material to be jigged or transversely thereto,or are inclined at any angle to it, may be determined. according to theparticular conditions and purposes.

The accompanying drawings illustrate settling machines provided withcorrugated carriers according to the present invention.

Figure 1 is a transverse section through a settling machine of simpleconstructional form, and Fig. 2 is a plan view of Fig. 1. Fig. 3 is atransverse section through another constructional form. Fig. 4t is afront view of Fig. 3, partially in section on the line A-B. Figs. 5 to13 are diagrammatic transverse sections of various improved carriers.

The machine consists of one or more re ceptacles B, which are arrangedone beside the other and are filled with water. A piston K is moved upand down in each receptacle B and forces the water to pulsate to and frothrough the underside of the carrier a upon which the material to besepa- Specification of Letters Patent.

rated is supported. Owing to the augmentation of the superficial area ofthe material carrier obtained by the corrugations the jigging action isincreased in an admirable manner. The heavy material settles in thetroughs of the corrugations from which it can be easily removed, whilethe lighter material rises to the top and passes out in the longitudinaldirection of the machine, that is, in the direction of the feed of themachine or the direction in which the material is transported from onesettling section to the adjacent one.

In the constructional form shown in Figs. 3 and 4, a delivery mechanismis provided by which the advantages of the use of corrugated materialcarriers are still further increased. The delivery of the heavy materialtakes place in this constructional form from the troughs of thecorrugations. In consequence thereof, the major portion of the uppersurface of the material carrier remains accessible to the free andunimpeded jigging action, an accumulation of the settled material takingplace in the troughs of the corrugations. In this case, considerableeconomy in driving power is effected, because the water is not compelledto set the comparatively heavy settled material in motion.

An additional advantage is that a more rapid delivery of the settledmaterial is set up in addition to the improved action of the uppersurface of the material carrier. At the same time, considerably lessgrinding action takes place which must be regarded as a great advantagein the operation of concentration. In the present construction, thedelivery of the settled material from the troughs of the corrugations iseffected into a delivery receptacle placed at the side of the machine.The corrugated material carrier a is preferably arranged at a slightincline toward this receptacle in such a mannor that the channels ordepressions formed run toward the wall Z) of the settling machine towhich the receptacle 0 is attached. This latter is connected to thesettling machine by a number of pipes (Z, which open inside the machineexactly over the bottom of the trough of each corrugation so that thesettled material is compelled to pass into receptacle 0 by the shortestroute and in proportion as the delivery.apparatus 0 arranged at the footof this accumulating receptacle allows it to flow away.

To enable the machine to be worked conveniently, it is necessary thatthe delivery of the settled material shall be effected uniformly fromall the troughs of the corrugations. This, however, can only beaccomplished when the delivery of the settled material which collects inthe accumulating receptacle is so regulated that the surface of thematerial forms a uniform plane which is situated at the same level asthe delivery openings of the troughs, In order to eifect a uniformdelivery of the settled material, damming devices are provided, whichpurpose is served by the inserted pieces marked 7. The particular way inwhich these latter are arranged and their shape depends upon theconditions of the particular work being done, The lateral delivery ofthe settled material employed in the present case possesses the greatadvantage that it enables the jigging process to be inspected and accurately controlled. It is obvious of course that the delivery of thesettled material may also be effected in other ways.

I claim:

1. A jigging machine, comprising a water receptacle, a stationaryperforated carrier for exclusively supporting the materials to beseparated mounted over said receptacle, said carrier having corrugationswhich act to increase the area of its operating surface, and meanscausing water from said receptacle to pass upward and downward throughsaid perforations, the upward passage of the water serving to raise the.material and thereby effect the separation of the different materials onsaid carrier according to their specific gravities, substantially asdescribed.

2. A jigging machine, comprising a water receptacle, a stationaryperforated carrier for exclusively supporting the materials to beseparated mounted over said receptacle, said carrier having corrugationswhich act to greatly increase the area of the operating surface of saidcarrier and the number of perforations for a given size of carrier, thesaid corrugations serving also to increase the strength of the carrierso that the latter is enabled to carry the whole load of the materialswithout the aid of a frame, and means for causing water to pass back andforth through said carrier in jerks to carry the various materials onsaid carrier upward to different heights according to their specificgravities, the various materials settling upon the carrier indiiferentlayers or zones according to their specific gravities,substantially as described.

3. A jigging machine, comprising a water receptacle, a stationarycarrier for exclusively supporting the materials to be separated, saidcarrier having openings there through and being mounted over saidreceptacle, and means for passing a pulsating current of water from saidreceptacle upwardly and downwardly through said openings for producingthe settling action, said carrier being formed with corrugations toincrease the number of openings and reduce the resistance to the passageof the settling water through the carrier, substantially as described.

4:. A jigging machine, comprising a water receptacle, a substantiallyhorizontal stationary carrier mounted over said receptacle and formedwith a plurality of vertical folds or corrugations which increase thestrength of the carrier so that the latter is enabled to carry the wholeload of the materials to be separated without the aid of a frame, saidfolds or corrugations being perforated, the perforations in di ferentportions thereof extending in different directions to direct water jetsagainst the materials on the carrier at difierent angles, to gether withmeans for forcing liquid upwardly through said perforations from saidreceptacle, substantially as described.

5. A jigging machine comprising a stationary corrugated carrier havingthrough openings therein, a water supply, means for causing said waterto pulsate through the said openings, and a discharge and regulatingvessel adjacent to the settling machine adapted to receive the settledmaterial from the carrier, the carrier being arranged to discharge thesettled material at an angle to the direction in which the material istransported over the carrier; substantially as described.

6. A jigging machine comprising a stationary carrier having corrugationswhich increase the area of the carrier, there being a plurality ofperforations through the carrier, means for pulsating water through saidcarrier, a discharge and regulating vessel extending longitudinally ofthe machine at the side thereof, there being openings through the sideof the settling machine leading from the carrier into the discharge andregulating vessel, said openings being formed immediately above thecorrugations in the carrier; substantially as described.
